What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Postoperative education is an important component of recovery after coronary artery bypass grafting (CABG), but its overall effects on psychological, self-management, and quality-of-life outcomes remain unclear. This systematic review and meta-analysis aimed to evaluate the effects of postoperative educational interventions in patients undergoing CABG. Methods: PubMed, Web of Science, Embase, Cochrane Library, Scopus, and CINAHL were searched from inception to March 2026. Randomized controlled trials (RCTs) enrolling adult patients undergoing CABG were included if they compared postoperative educational interventions with routine care. Meta-analysis was conducted using Stata/MP 18.0. Pooled effects were calculated as standardized mean differences (SMDs) with 95% confidence intervals (CIs). A random-effects model was used when substantial heterogeneity was present; otherwise, a fixed-effect model was applied. Leave-one-out sensitivity analyses were performed when appropriate. Results: Fourteen studies involving 1,669 participants were included. Postoperative educational interventions significantly reduced anxiety (SMD = -0.48, 95% CI: -0.87 to -0.08) and depression (SMD = -0.42, 95% CI: -0.71 to -0.14), and significantly improved physical functioning (SMD = 0.30, 95% CI: 0.08 to 0.52). Mental functioning showed a favorable but non-significant trend (SMD = 0.26, 95% CI: -0.01 to 0.53). The pooled effect on self-efficacy was not statistically significant (SMD = 1.08, 95% CI: -1.12 to 3.29), with substantial heterogeneity. Self-power improved significantly (SMD = 0.54, 95% CI: 0.19 to 0.89), but this finding was based on only two studies. Subgroup analyses suggested that intervention effects varied according to the dominant intervention format. Conclusions: Postoperative educational interventions appear to reduce anxiety and depression and improve physical functioning in patients after CABG. However, the current evidence does not support significant improvements in mental functioning or self-efficacy. Given the limited number of included studies, the finding for self-power should be interpreted cautiously.
